Safety Precautions
When operating heavy equipment, the efficient operator will be guided by simple and fundamental rules of safety. He will always take the necessary precautions to ensure the safety of others as well as himself. He will avoid careless operating habits which cause damaging accidents to machinery and equipment.
In order to help prevent accidents, the operator should follow these general safety rules and precautions:
Watch Load at All Times. Watch the load while it is moving. In case you have to look in another direction, stop operation at once.
Back Away from Dangerous Banks. Do not leave the machine near a bank that is liable to cave. In such cases, back out and away from the bank if machine is to remain idle for some time.
Use Sufficient Parts of Line for Heavy Crane Lifts. To obtain maximum lifting capacities the hook block must be reeved with sufficient parts of line.
Do Not Leave Machine With Load in Air. Never leave the machine with a load in raised position.
Avoid Greasy Machine. Keep turntable deck free from grease and mud so as to prevent slipping and falling.
Replace Worn, Dangerous Cables. Do not operate with broken, worn or frayed cables. Install new cables when old ones give indication that they might fail. (See "Wire Rope Inspection.")
Stop Machine When Lubricating or Adjusting. It is essential to stop all operations when cleaning, adjusting, or lubricating the machine.
Always Idle Engine Before Stopping. The engine should always be throttled down to idling speed before turning off the ignition.
Watch Clearances When Traveling. Avoid running into overhead or side obstructions. When moving in tight quarters, post a lookout to help guard against collisions or bumping into buildings.
Check Load Capacities of Bridges. When traveling across country bridges, first check to make sure they will carry a load equal to the machine's weight.
Always Keep Boom at Least Six Feet Away From All Overhead Wires. If boom should hit overhead wires, stay on machine until boom is cleared or current is cut off. Keep everyone on the ground away from machine. If you must leave the machine - jump, do not step off.
Keep Everyone Away from Beneath Loads. Use handlines for guiding loads.
Never Swing Over Ground Men.
Inspect All Cables and Clamps Weekly.
Never Get On or Off a Machine in Motion.
Check Slings Before Lifting. Check to be sure all slings, ties and hooks are properly placed and secured before raising or lowering loads.
Check Capacity Chart in Cab. Always refer to capacity chart in cab before making heavy lifts to determine the safe lifting radius for the load.
Replace Guards. Always replace all guards immediately after completing lubrication or adjustment. Remove and store all tools before resuming operation.
Maintain Proper Tire Inflation. Check daily and maintain proper tire inflation in tires on all wheels for best operation and longest tire life, particularly when working on rubber without outriggers.
CAUTION: Never pull side ways with a crane boom. Crane booms are not designed for excessive side pull and may collapse if subjected to excessive side loading.
CAUTION: Do not rely on machine tipping stability to determine capacity. Refer to the capacity chart for the machine. Do not exceed the capacities shown on the capacity chart.
